Abstract

The combined two-dimensional display digital pixel and micro sensing matrix device comprises several pixel components and at least a sensing component allocated at the isle outside the pixel component, with these sensing component and these pixel components up and down layer connected to the column address conductor, with each scanned signal applied to these address conductor, each data signal of the drive circuit applied to these pixel component through the address conductor, a detecting circuit connected to the address conductor to test the sensing element. It allocates these sensing components on the TFT matrix base or the isle between the colored filter base pixel components to reduce loss of transmittance ratio, increase the overall openness.

Description

technical field [0001] The invention relates to a combined matrix pixel and sensing device, in particular to a device that utilizes current liquid crystal display lithography manufacturing technology combined with related sensing components such as light sensing, capacitance, resistance, and electromagnetics, so that the flat-panel display can simultaneously It has display and input functions, increasing the applicability of the product.
